Once you install test pipes or the Motordyne arts pipes your Z will be loud with a lot of volume enough to wake up the dead. If you like your Z not being that loud the resonated AAM Competition test pipes is an option they are very slightly quieter than the non resonated AAM Competition test pipes. Catback exhausts will only amplify the sound and make your Z louder.
